A crash involving an Amtrak thruway bus and at least four other vehicles snarled traffic on Interstate 405 near downtown Portland Friday.

The crash was reported about 4:30 p.m. between Southwest Salmon Street and Jefferson Street and initially blocked all the northbound lanes. All the involved vehicles have since been removed from the scene and traffic is apparently moving freely through the area.

A man in his 40s and the bus driver have been taken to the hospital
with non-life threatening injuries, said Lt. Joseph Troncoso, a Portland Fire and Rescue spokesman. No other injuries have been reported.

The Amtrak motorcoach was heading to Portland from Eugene and none of the 35 passengers were hurt, said Marc Magliari, a company spokesman.

Details on what caused the crash have not been released and Portland police is investigating.
